If I only knew Bitcoin 10 years ago, I would have probably invested, only if I had a mindset of an adult that time of course, but since we were so young that time, well at least for me   , I think it's impossible that we'd focus on Bitcoin instead of our academics and enjoying our childhood, but if I was only this aware on how big Bitcoin will be in the future, I seriously would have bought and tried to buy when BTC used to be very cheap, it sucks to have regrets but at least we're making progress now, it's never too late to start investing.
